🎭 Social Psychology: Groups and Prejudice
The Story of the Playground
Imagine a big playground. Kids everywhere! Some play alone. Some form groups. And sometimes… groups don’t play nice with other groups.
This is Social Psychology — understanding how people act when they’re together and why sometimes they treat others unfairly.
🌊 Group Influence: The Wave Effect
Think of a stadium doing “the wave.” One person stands up, then the next, then the next. Soon, EVERYONE is doing it!
That’s group influence. When we’re around others, we change how we act.
Why Does This Happen?
graph TD A["You in a Group"] --> B["Want to Fit In"] B --> C["Copy What Others Do"] C --> D["Group Shapes Your Behavior"]
Simple Example:
- You’re at a new school
- Everyone claps after a presentation
- You clap too — even if you didn’t love it!
The Magic Rule: Groups are like magnets. They pull our behavior toward what everyone else is doing.
⚡ Social Facilitation: The Audience Boost
Ever notice you run faster when someone is watching?
Social facilitation means you do BETTER at easy tasks when people watch you.
The Bicycle Race Discovery
In 1898, a scientist named Norman Triplett noticed something weird. Cyclists raced faster against others than alone!
Here’s the trick:
| Task Type | With Audience | Why? |
|---|---|---|
| Easy task | You do BETTER | Energy boost! |
| Hard task | You do WORSE | Too nervous! |
Example:
- Tying your shoes (easy) → Faster with friends watching ✅
- Solving hard math (difficult) → Slower with people staring ❌
Remember: Being watched is like coffee for easy tasks. But for hard stuff? It’s like drinking too much coffee — jittery!
😴 Social Loafing: The Lazy Group Problem
Ever worked on a group project where some people did NOTHING?
Social loafing = people work less hard in groups because they think “someone else will do it.”
The Rope Pull Experiment
Scientists asked people to pull a rope as hard as possible.
- Alone: Pulled with 100% effort
- In a group of 8: Each person pulled with only 50% effort!
graph TD A["Working Alone"] -->|100% Effort| B["Maximum Work"] C["Working in Group"] -->|50% Effort| D["Everyone Relaxes"] D --> E["Less Total Work"]
Why does this happen?
- “My effort won’t be noticed anyway”
- “Others will pick up my slack”
- “No one is keeping score”
Fix It: Make each person’s job clear and visible!
🗣️ Group Decision Making: When Heads Don’t Add Up
You’d think more brains = better decisions. But groups can make TERRIBLE choices!
Groupthink: The Dangerous Agreement
Groupthink happens when everyone agrees too fast because no one wants to rock the boat.
Warning Signs:
- 🚨 No one asks “What if we’re wrong?”
- 🚨 People afraid to disagree
- 🚨 “We’re too smart to fail” attitude
Famous Example: NASA’s Challenger disaster. Engineers worried the shuttle wasn’t safe, but no one spoke up against the group.
Group Polarization: Going to Extremes
When groups discuss something, they often become MORE extreme.
Example:
- You kinda like pizza 🍕
- Your friends LOVE pizza
- After talking, you ALL become pizza fanatics!
graph TD A["Mild Opinion"] --> B["Group Discussion"] B --> C["Stronger Opinion!"] C --> D["Even MORE Extreme!"]
Why? You hear more arguments for what you already believe. Plus, you want to fit in!
😠 Prejudice: Judging Before Knowing
Prejudice = Pre + Judge = judging someone BEFORE you know them.
It’s like deciding you hate a movie without watching it!
The Three Parts of Prejudice
| Part | What It Is | Example |
|---|---|---|
| Feelings | Negative emotions | Feeling scared of a group |
| Thoughts | Beliefs (stereotypes) | “All ___ are ___” |
| Actions | Discrimination | Treating people unfairly |
Simple Example: A kid sees someone wearing different clothes and thinks, “They must be weird. I won’t play with them.”
That’s prejudice. They judged without getting to know the person!
📦 Stereotypes and Discrimination: Boxes and Behavior
Stereotypes: Mental Shortcuts Gone Wrong
Stereotypes = putting people in mental boxes based on their group.
Our brain LOVES shortcuts. Instead of learning about each person, it says: “Oh, they’re from Group X, so they must be like…”
The Problem: These boxes are often WRONG and unfair!
Example:
- “All old people are bad with technology” ❌
- (But your grandma might be a coding expert!)
Discrimination: When Thoughts Become Actions
Discrimination = treating people DIFFERENTLY because of their group.
graph TD A["Stereotype - Thought"] --> B["Prejudice - Feeling"] B --> C["Discrimination - Action"] C --> D["Someone Gets Hurt"]
Examples of Discrimination:
- Not hiring someone because of their name
- Not letting someone join a game because of how they look
- Paying someone less for the same work
🔍 Sources of Prejudice: Where Does It Come From?
Prejudice doesn’t appear from nowhere. It has SOURCES!
1. Social Learning (Copying Others)
Kids aren’t born with prejudice. They LEARN it.
- Watching parents act scared of certain people
- Hearing jokes that put down a group
- Seeing movies that always make certain groups the “bad guys”
2. Us vs. Them Thinking
Our brain loves to sort: “MY group” vs. “OTHER groups”
The Minimal Group Experiment: Scientists divided people randomly — by coin flip! Within MINUTES, people favored their own group and disliked the “other” group.
Even meaningless groups create “us vs. them”!
3. Competition for Resources
When groups fight over limited things (jobs, money, space), prejudice grows.
Example: Two groups both want the same park for their team practice. Suddenly, each group thinks the other is “terrible.”
4. Scapegoating: Blame the Other Group
When things go wrong, it’s easy to blame someone else.
The Pattern:

🌈 Reducing Prejudice: Making Things Better
Good news! Prejudice can be REDUCED. Here’s how:
1. Contact Hypothesis: Getting to Know Each Other
The idea: When different groups spend QUALITY time together, prejudice shrinks!
But it only works if:
- ✅ Both groups have equal status
- ✅ They work toward a common goal
- ✅ They have support from authorities
- ✅ They get to really know each other
Example: A sports team with kids from different neighborhoods. Working together to win, they become friends!
2. The Jigsaw Classroom
A clever teacher technique! Each student has ONE piece of information the group needs.
How it works:
- Split students into diverse groups
- Each person learns one part of the lesson
- They MUST teach each other
- No one succeeds unless EVERYONE shares
Result: Kids from different backgrounds become teammates, not rivals!
3. Common Goals: Fighting Together
Remember the “us vs. them” problem?
Fix it: Create a BIGGER “us”!
Example:
- Two rival schools
- A storm damages both
- They work together to rebuild
- Now they’re allies, not enemies!
4. Perspective-Taking: Walk in Their Shoes
Simply IMAGINING being another person reduces prejudice.
Try this:
- Pick someone different from you
- Close your eyes
- Imagine ONE day in their life
- How do they feel? What challenges do they face?
Studies show: Just doing this exercise makes people kinder!

🌟 The Big Takeaway
We’re ALL influenced by groups. Sometimes for good (teamwork!). Sometimes for bad (prejudice).
But here’s the amazing part: Once you KNOW how this works, you can:
- Resist lazy group thinking
- Catch yourself stereotyping
- Build bridges instead of walls
- Make ANY group better
You now have superpowers for understanding people. Use them wisely! 🦸♀️🦸♂️
